Harmonic Multivalent Functions Defined By General Integral Operator, Mays S. Abdul Ameer, Abdul Rahman S. Juma, Raheam A. Al-Saphory

Al-Qadisiyah Journal of Pure Science

The main aim of the present work is to introduce the class of multivalent harmonic functions defined by the general integral operator. Thus, We get some geometric properties, like coefficients estimate, extreme point and distortion theorem, convolution property, radii of starlikeness, and convexity.


Some Properties Of Univalent Function With Negative Coefficients Defined By Using A Linear Operator In The Open Unit Disk, Teba Rzaij Sabah, Abdul Rahman Salman Juma Jul 2020

Some Properties Of Univalent Function With Negative Coefficients Defined By Using A Linear Operator In The Open Unit Disk, Teba Rzaij Sabah, Abdul Rahman Salman Juma

Al-Qadisiyah Journal of Pure Science

In this paper, we introduce and study the subclass R()of univalent function with negative coefficients by using new linear operator in the open unit disk. We obtain some geometric properties like coefficient inequality ,growth and distortion theorem. Hadmard product ,extreme point, closure theorem and radii of starlikeness, convexity and close-to-convexity of functions belonging to our subclass.
